Cellular Respiration Notes

Cell Respiration Equation

C₆+ H₁₂+ O₂ = 6CO₂+ 6H₂O + ATP

Glycosis Overview

Glucose is broken down in to 2 pyurvates and NADH and ATP are made

Kerbs Cycle Overview

Pyurvates are further broken down and NADH, FADH₂ and a small amount of ATP is made

ETC Overview

NADH and FADH₂ power the formation of H⁺ gradient and H⁺ leading to the formation of many ATP molecules

Glycosis occurs where?

Cytoplasm

Input starts with 6 carbon molecules then how many are in the end?

3 carbons

Is oxygen needed in glycosis?

Oxygen is not need in the first step of cellular respiration

Glycosis Inputs?

Glucose and 2 pyurvates

Outputs of Glycosis?

2 NADH and 4 ATP and 3 Carbons

What is the transitional step of the Kerb’s cycle?

Pyurvates entering the mitochondria

Why are pyurvates further broken down?

To energize NAD⁺ and FAD

Kerbs Cycle Inputs?

2 pyurvates

Kerbs Cycle Outputs?

6CO₂ and 8 NADH and 2 FADH₂ and 2ATP

What are the electron carriers in the ETC?

FADH₂ and NADH which release electrons into the ETC

High energy electrons pump what into the intermembrane space?

Hydrogen is Pumped

What pass through the ATP synthase while producing many ATP?

H⁺ ions

What is the final acceptor of cellular respiration?

Oxygen

What does oxygen form with the electrons to get rid of excess electrons?

Water

What cannot function without oxygen?

ETC

Where does NAD and FAD return to once finished in the ETC?

Glycosis and the Kerbs Cycle

Main Idea Of Cellular Respiration?

Cellular Respiration harvests the energy from the food we eat to make ATP.

Since Oxygen is the final electron acceptor what does it take away through water?

Excess H⁺ and Electrons

Main Idea of Glycosis

Summary: Glucose gets turned into 2 pyurvate acids

Main Idea of the Kerbs Cycle?

Summary: Breaks down pyurvates to energize NADH and FADH_2, to release CO2

Main Idea of the ETC?

Summary: Creates an hydrogen gradient to make many ATP

How many ATP are made in the ETC?

38

One glucose is how many pyurvate

2

How much smaller is the pyurvate to the glucose molecule

1/2

Which type of respiration requires oxygen?

Aerobic

Does glycosis occur in both respirations?

Yes

Describe the function of cellular respiration

When there is no oxygen for cellular respiraton what path does it take?

Anaerobic Respiration

In Anaerobic Respiration how many ATP are produced?

2 ATP are made in the alternative pathway

What are the two most common fermentation?

Lactic Acids and Alcoholic Fermentation

Where does Anaerobic Respiration take place?

In the cytoplasm
